To aZZ 'whom t may concern v Be it known that l, WILLIAM E. Rinne, of Manseld, vin the county of Bristol and State of Massachusetts, have invented a newl and useful Grate, of which 'the-following is a specication.

l have Vobser/ed'that in grate constructions heretofore the clinkers collect upon the walls surroundingv the re' to such an extent that the edges of. the mass ol .tuel

. will not have proper combustion and in some cases` the agglomeraticn ol material is so great that the combustion otthe body of the' fire isv interfered with. en attempts have been made to remove the inaterial it has been iound not only to be a very dicult matter butv portions ot the v'walls themselves .arel removed and the walls loe-- come pitted and materially weakened.

'The main object ot my invention is to overcome these detects which l -do by" providing a removable fuel.. V

fas

Other objects are to provide an ecient draft and escape tor the fuel at the' edges of the mass andA these objects l attain by providing a grate surface around the hre. @ther features of my invention vwill be pointed out below..` v

lin the drawings. Figure l -is a'perspective ot a grate wall embodying my invention; Fig; 2 is a partial section online 2420i Fig. l; Fig. 3 is a section showing. 'the several members ot the retaining grate surface' and the adjacentl supporting grate bars; Fig.. t is an elevation.oitthe supporting plate; lig. 5. is a side viewthereo g Fig. 6 is an elevation ot two adjacent supporting plates, these being slightly diderent from' the supportingplate shown in Fig. el; Figs..

g. 13; Fig. l5 is asectionot one of said modified posts; and hhg; lo is-'aper-- shown part but has two portions e c projecting' from its side with lugs c e at the end thereof at right angles thereto forming hoolrs.A 'llhese specification or Letters raient. partance@ Nam 2319 img,

applica-apn met reentry a?, ien. terni no. einem portions e e enter recesses in the wall' and are held to it by placing bricks in position in front of' said lugs. Each plate also has a horlzontal lug e2 projecting from its tace and also a vertical central lug e3 and lugs e4 e at an acute angle with the horizontal as well as supporting lugs e5 e5 and spacing lugs es at the rear. Eachl plate is also cut away at e" tor a purpose to be presently described. 4'lfhese supporting plates rest on the irebrick portions D and Din Fig. -lv but in 13, 14 and l5 l show cast metal posts'D. 3

and D4, D2 and D8 being at' the center ol Athe wall and Dl being at the end;

these members being rounded to facilitate cleaning ot the ash pit. 'lhe posts maybe held to the wall in any suitable way and the posts D2 and D3 may be bolted together.

'lhe uel supporting grate bars B .which Hsupport the uel are adjacent to the'retaining grate surface which retains the fuel on the supporting bars and which in thedrawi ings comprises upper member F, intermediate members@ G and lower member ll.'

" Upper member l", preferably ot metal,

comprises web f and lugs f v", the top of the .lugs being horizontal and the sides ot the lugs forming a vertical fuel retaining surface the web f being at an obtuseangle to' l 4'more fully hereinafter derfwribed.V linter- 'said vertical surface. 'The lug ,t2 at the .end Y mediate member G lcomprises web g which tapers slightly toward t Lower member Vll comprises vertical retaining surface it having ypertorations it, two parallel websl? 7b2 at an acute angle e rear and-spacing y I lugbsv gf whose tops' are parallel with the.

with the retaining's'urtace and spacing lugs ha k3 whose tops areparallel with the webs.` Anydesired form of openings or perforations may be had inv place of those l have v'shown andlin place ot member H l may use ,member K shown'in Fig. 16 in which there tot is a single web c and" in which the portions la act as spacing lugs.

In assembling `the parts l place memberv F inposition beneath portion L of the Wall and the tops of lugs f support the vvall,v Member F is supported by plate E by means 'prevent its movement toward the tire. lA

theninsert members Gr Gvvhich't in the opening e7 and v vhose movement towardthe Wall is limited by the vertical central lug c3.

'l have shovvn two members G but any de ,sired number may be used. 'lhe several members l, Gr andA ll form a retaining surface for the side ot the incl and as lit is desirable to allow-easy descent ot the ashes and tree circulation oli air-l use the lugs described to space the vvebsvot the various* v members, it being clear that there is suchfa space above vveb f and between the several Webs all ot which slopesvdovvnwardly avvay till `trom the dre. lt will also be noted that .ll

provide an .airspace 'ld at the'rear oi the.

loosely to allovv for expansion ot the parts.,A

lll ith my iron constructionA oi bars the clinlrers will not form thereon and yet the 'iron vvill not melt because oi my provision for lull circulation oi' air, When the retaining surface is to be removed or repaired the members G il are slid upwardly avvay from the Wall and then the other members are removed trom position.,

lt may bey desirable to have the lovver por tion 'of the retaining grate surface farther from the Wall than the upper 'portion and in that case l may construct the grate surtace obliquely as shovvn in'lTig. 9 or convex as in llig. 7 or concave as in Fig. 8, I

lt vvill'be clear that my grate has the important advantage ot providing proper combustion for all portions oi the tuel and that consequently the Waste oil fuel is much decreased; that the time and labor required for renewing or repairing is much reduced and that the structure is simple and cheaply made. lt will also be clear that l have in reality a retaining grate surface that isa adjustable to any desired height oi tire, and this is because l may use any desired number oi intermediate bars Without in any Way modifying the structure of the other inem-1 bers' of the grate surfacea l ll do not claim the retaining grate elements as such nor the supporting plate as suchinor the downwardly and inwardly eti-- tending retaining surface as such in this application as l intend to make those features* the subject ot anotherl or other applications.
